I don't think the title-text references leap seconds, as it says that "many" are wrong, not "all". It seems more likely it refers to stores that claim to be open 365 days per year, and are hence wrong in leap years. 20:12, 17 April 2017 (UTC)

I agree that it would be closed for 39 (and a bit) minutes a day if it was open for exactly 24 hours. I think Randall made a mistake. 21:30, 17 April 2017 (UTC)

The parts in the description that talk about mixing "Earth and Mars time units" and "Mars-hours" don't make sense; I'm pretty sure there's no such thing as a Mars-hour. Despite the classical definition of an hour (which has since been replaced), an hour is defined as a number of seconds, and seconds are an SI unit based on the characteristics of Caesium-133 atoms...NOT defined as being a fixed fraction of a day. Even the unit "day" is often used to refer to a fixed unit of time nowadays (defined by the SI to be 86 400 s)...I believe this is one of the reasons why the solar day on Mars is referred to as a "sol" instead of a "day". 22:15, 17 April 2017 (UTC)

Nitpicking a bit, but the day is usually only 86400 seconds long (see 1481).
That's what I meant to say, SI defines it to be 86 400 s; I have no idea why I typed 86 401 s. It is fixed now. 15:39, 18 April 2017 (UTC)
NASA's Mars Mission do divide the "sol" into 24 "Hours". I thought about adding this as a clarification the the Mars-Hours but that made the sentence somewhat unwieldy. 09:27, 18 April 2017 (UTC)

Fun fact that might be interesting to add to the note about Arizona and DST. As stated already, the Navajo reservation observes DST, since it extends into Utah and New Mexico. However, the Hopi reservation, which is entirely enclosed by the Navajo reservation, does NOT follow DST. So in the one state in the Mountain Time Zone that does not observe DST, there is a region that follows DST, and inside that is another region that does not follow DST. 01:28, 18 April 2017 (UTC)

And looking at a DST map of Arizona, it appears there is at least one small area contained within that inner-most non-observing region that does observe DST... 08:11, 18 April 2017 (UTC)
Up through 2006, some of Indiana didn't observe DST. That really screwed with my college career, being from Virginia. Some of the time I'm on DST, others I'm not.
